Definitions
- the present invention relates to a color and gray balance adjustment system for electrophotographic printers and copiers, and more particularly, to an apparatus and method for permitting users and technicians to perform color and gray balance procedures according to improved corrective procedures.
- Figures 1 through 5 show system 100 of the present invention for adjusting color and gray balance in a printer or copier (not shown).
- system 100 is initiated according to block 102, all color adjustments are set (or reset) to nominal or center values so as to permit adjustment in both directions.
- a print command is initiated so as to print out a copy of the test pattern for evaluation.
- the test pattern of Figure 5 is evaluated to determine if the printer is operating within specifications. The relative magnitude of any adjustments that may be required to the system may also be evident when the Figure 5 test pattern is initiated.
- the "most neutral" gray patch in pattern 190 shown in Figure 5 is selected.
- test pattern 220 includes seven squares, each having a centered gray target in the center of each indicator patch.
- Color balance in a copier may be completed by following the same procedures as adjusting printer color balance, except a test pattern 220 is copied from the platen and used to adjust color balance.
